José Manuel Alvarez, also known as Dubbyman, made his debut as a DJ in 1992, hidden under the name of José Vertice. Acid house, funk, drum&bass and hip hop were just some of the ingredients of his firsts sets, backed up by his collective Dogs Connected.

Latter incursions into dubbed house and electrofunk sounds took him to visit most important clubs in Madrid like Deep and Danzoo, while maintaining his own club, Freak. By 2002, and thanks to his new facet as a producer he became Dubbyman, moves his residency from Freak to Café Bar Las Descalzas and expands his sessions across Madrid, in clubs like Morpheus, Ohm, Taboo, Deep, Danzoo,or Goldfield and outside, in places like Le Club (Valencia), El Sol (Salamanca), Telefunken, House café, Foxx (La Coruña), La casa de la música (Badajoz).
